8.8:1 or whatever the stock 1.8 CR is. 265cc tan tops. Nothing special beside the cam swap and camgears.

I was scared to even run 13.4:1, I guess I won't be any more.

Thats what I was about to do. I thought I read somewhere that these motors liked to be around 12.5-13.0 max, but based on those numbers, I will be revisiting that theory.
